Transmission Link Planning Tool for Excel™

(Version 7b - February 13, 2015)

Mr. Alok K. Tiwari, of Idea Cellular Ltd., has graciously made this "Transmission
Link Planning Tool" workbook available. Says Mr. Tiwari, "Based on users feedback regarding some of the
buttons not working properly, I have just gone through the sheet to make those necessary corrections in the macro
used. Almost no change has been made in formulas." Please also see the UMTS Link Planning Tool as well.

Important: If the file name is changed from the supplied
"Link Planning Tool.xls," some of the macros will not function properly. It would be best to save the completed
workbook under a new name, then start on new systems with the original file.

Here is the description for using the utility: 1. We mainly enter the parameter value into the
sheet "Calculations". a. Entries shown in YELLOW cells are
mandatory. b. Entries shown in GREY cells are to play with in order
to get the desired result wrt Standard Link
Design Criteria. c. Entries shown in SEA GREEN are ONE-TIME entries
like temperature, pressure etc.

DISCLAIMER: Use of this UTILITY is not intended for any commercial
set-up. The author is not responsible for any type of damage occurred due to implementation of the results obtained
from this utility to any commercial set-up.

Please
be careful while making any change to Sheet "Calculations" for it contains the most important formulae. Passwords
can be provided if needed (aktiwari@hotmail.com).

The "Calculation" sheet looks up for the required data :
a. For Antennae (of 18 GHz band) from the sheet: "DB_Ant1
(18GHz). b. For Antennae (of 15 GHz band) and Frequency of
Operation from the sheet:"DB_Ant2 (15GHz).
Note that only FOUR antennae sizes EIGHT Frequencies in TWO
separate bands can be used. c. For Radio Specific Data form the sheet:
DB_RadioEqpt. Here THREE different type of Radios can be used.

2. The Sheet "Antenna Heights" is to calculate the antennae
heights based on LOS survey feedback data.

3. The Sheet "Report" is just the compilation of information used
in link implementation.

This is to bring to your kind notice that formulae used into this workbook are as per ITU-T.As I'm using the
Tool like Nokia's NETACT PLANNER and CTE's PATHLOSS, I've observed the similar results at least for Link Design
parameters.

NEW (v7a): "Technical Information"

1. Back-to-back coupled Passive Repeater calculations. 2. To make this spreadsheet more
useful I have made this spreadsheet more user friendly by putting some "buttons"
so that one can select the values by using these buttons without typing or looking for the other
sheets. 3. Provision to view/analyse the link graphically ( Addition of : Path Profile) over a approximated
Terrain. 4. A "Technical Information" page has been added in order to have easy understanding of the principles
involved in a Microwave Link Designing. Also, more automated buttons have been
added. 5. Now you can select any one of the THREE frequency bands, namely 15 GHz, 18 GHz and 7 GHz.
Each band is provided with 6 frequency spots. The same provision is there for
Radio selection too. 6. Added the provision to use this utility globally and it can be done just
by selecting the appropriate part of the globe. Additionally, the facility to
explore different type of geographic clutter has also been introduced. Passwords
can be furnished on request.

NEW (v3): Selection Buttons

To make this spreadsheet more useful I have made this spreadsheet more user friendly by putting some "buttons"
so that one can select the values by using these buttons without typing or looking for the other sheets.
